Firefox can't open. HTML files

I use Firefox 14.0.1. I can't open any sort of. File HTML (written in Notepad) in Firefox when in other browsers, I can open these normally. When I try to open my HTML file to test in Firefox, they could not be opened rather than I get some not sorted as Chinas scripts or something like that (I don't know clearly what kind of language)
I do not understand what to do?
Thank you in advance for your help.

A few questions about your HTML file.

First of all, using unusual fonts? "Outline" or "vector" fonts usually give more reliable results in browsers. It is Arial, Times New Roman, and Courier New.

Second, you get different results if you use file > save as (in Notepad) and change the ANSI or UTF-8 encoding? I think that those who are the most commonly used for web pages. The drop-down list coding is just to the left of the button Save.

    Former title: can't open html files by double-clicking after Windows update

    Hello

    After today update Windows I can't open html files in my browser (SeaMonkey) by double-clicking on it in Windows Explorer. Nothing happens when I double click on it. .html extension is always associated with SeaMonkey.

    Is there some security settings changed?

    By the way: Windows Update should never restart Windows without asking. This is really a no go! I changed the settings to update manually now installation and the hope that restart without asking will not happen.

  • I can't open pdf files in firefox, and I tried all the solutions proposed by others. How can I reactivate pdf in firefox?

    I have recently switched to Firefox to Google Chrome, and I find that I can't open all PDFs from the web in some way in Firefox. I can't download them and open them in Adobe Reader and I can't preview them in Firefox, or I can use the plugin from Adobe. I tried to use the solutions posed by users on this site, but none of them have worked. Whenever I have an amendment to the settings to try to resolve this problem, change never allows me to view the pdf file, and the setting reverts to the previous setting after the browser is restarted. I don't like how to display the file, but I need to be be able to see a preview or I need to be able to download it.

    I use an adobe download add-on, 3.0.0.2, and I have disabled. Now, I can actually open pdf files in my browser shows a preview, or download them as I see fit. Thank you!

    But clearly, there is an error with the add-on.

  • Help? Adobe Acrobat Standard 11 - just bought for windows 7, now I can't open pdf files or tie?

    Help!

    I just bought the last Adobe Acrobat XI Standard.

    I put in the serial key number but my computer tells me that calling a product is not found on my computer so I can not use the adobe product. So now I can't open any file or attach PDFs to emails without this message coming. I uninstalled the "Adobe Acrobat XI Standard twice! with no luck.

    I need it sorted as soon as possible because I'm working! Any suggestions?

    DotBellaParis if you are prompted for a product calling it so it would seem that you purchased an upgrade to Acrobat Standard XI.  You should have the option to enter the serial number of your previous purchase of Acrobat.  You can find information on how to locate your previous issues of the series at http://forums.adobe.com/message/3987968#3987968?promoid=KBHJW.

    If you did not intend to buy an upgrade, then I recommend to submit a return request.  You can find more information on the presentation of a return to the return, cancel, or Exchange an Adobe order - http://helpx.adobe.com/x-productkb/policy-pricing/return-cancel-or-change-order.html.  Once you have returned the upgrade you can then buy the full version which will not ask you for an eligible product or a serial number.

  • Satellite Pro P300 - after Truesuite update I can't open protected files

    Hello
    Sorry for my bad English, but I came to Italy, and here we do not have any forum that can solve my problem.

    I have a Toshiba laptop pro P300 with fingerprint reader. I use fingerprints to log and protect certain files, simply out of curiosity, he seemed cool...: |
    The problem was born while I recently updated "truesuite access manager. Since I did the update I can not open protected files, I have not read that I have to remove the protection before the update (damn...), but these files are important to me and I have to reopen them.

    To solve the problem at all first I restore the system prior to the update to have the old version and open these files again, but my fingers are deleted and I can not create new prints because the pc said "could not open the sensor. I don't know what that means.
    I thought he needs some drivers, so I reinstalled truesuite Manager to access, several times, I reinstalled the BIOS, I did the scan of the drive and the diagnosis of toshiba, but the sensor still does not work.

    I think that if I can record a fingerprint with the old version of the program I will be protected able to open files again (and I will no longer protect them) because only the old version of the program knows how to decrypt these files, but I do not know how to enable the fingerprint sensor. Could someone help me, please?
    Thank you very much!

    The update of Truesuite comes WindowsUpdate? Or did you download the update from the Web from Toshiba site?

    You can use your backup password (usually its your Windows password) to access the files?
